Access to and reactions of P-functional 1,4-dihydro-1,4-diphosphinines fused to two TTF units

Abstract

P-functional phosphanylated tetrathiafulvalenes 3a–f were synthesised via stepwise lithiation and phosphanylation of TTF derivatives, and then reacted with PCl3 to form the related P-chloro compounds 4a–f. Reactions of 4c–f with...

Elimination reactions in 1,4-diphosphinine chemistry: mixed-valence intermediates and 1,1- vs. 1,4-elimination pathways

“…, incorporating 1,3-thiazole- and 1,3-dithiole-2-thiones 16,17 as well as different substitutions in C 2 -position, i.e. , selones, 18 TTF-motifs 19 and a 2-phenylimidazolium-fused example, the latter was reported by Ghadwal et al 20…”
